This example shows a multi-line chart plotting name frequency over time, with yearly data points connected to reveal temporal trends. The visualization uses D3 v5 with SVG rendering, mapping years to the x-axis and counts to the y-axis via `d3.scaleLinear`. It applies `d3.axisBottom` and `d3.axisLeft` for axes, and groups data with `d3.nest` before drawing paths with `d3.line`. A categorical color scale (`d3.scaleOrdinal`) distinguishes each name series.
